(you know this really isn't an advanced question)
You'd use "opendir" and "readdir" to get a list of the files, "open" to open the files, <HANDLE> to read the data from the file and probably "chomp" and "split" to process the data.
Why not show us what you've already got and explain where you are having problems.

Actually, I want to know how to go through each file, store value for the numeric field, calculate avg. I know how to opendir,readir, and open filehandle...

Have a hash where the keys are 'xyz', 'abc', etc. Use those to store a running total of the values. You'll also need another variable to store the number of files you have processed (so you can calculate the average).
Like I said before - show us the code. That'll make it far easier to help you.
